What Vehicles use Natural Gas?
CNG vehicles have been introduced in a wide variety of commercial applications, from light-duty trucks and sedans – like taxi cabs, to medium-duty trucks – like UPS delivery vans and postal vehicles, to heavy-duty vehicles like transit buses, street sweepers and school buses. In California, transit agency buses are some of the most prominent CNG vehicles.

Don’t want a Honda?
There are companies that specialize in converting other models to run on CNG. The Department of Energy says you can expect to pay between $2,000 and $4,000 for such specialty conversions. Chrysler, Ford, and General Motors offer heavy-duty CNG pickups for special-order from dealerships. All are available in a wide variety of body and drive configurations.

Infrastructure and Vehicle Availability
A wide variety of new, heavy-duty natural gas vehicles are available from U.S. original equipment manufacturers (OEMs). Although the number of available light-duty natural gas vehicles from original equipment manufacturers is limited, the choices are steadily growing. For availability, see the Alternative Fuel and Advanced Vehicle Search or the Clean Cities 2015 Vehicle Buyers Guide (Coming Soon).
Fleets and consumers also have the option of reliably converting existing gasoline or diesel vehicles for natural gas operation using qualified system retrofitters.

Natural gas vehicle costs:
Ford does not make natural gas cars, but some of its cars can be retrofitted into natural gas machines for around $10,000, said Gerry Koss, fleet marketing manager at Ford. That puts it in the high $20K and low $30K  range. Making cars that run natively on natural gas reduces the cost

Payback is easy to measure too, Russell says. A big rig might consume 20,000 gallons of fuel a year. If natural gas costs the equivalent of $2 per gallon, the driver or trucking company can saves $40,000 a year. A garbage truck might consume 10,000 gallons a year and cost $15,000 to retrofit. The retrofit pays for itself in less than a year and the truck might last seven years.

Range. A four-door CNG taxi with a tank that can hold the equivalent of 15 gallons of fuel can get close to 300 miles on a tank.
